That's because you have a AA0.4 core on the other side. As long as you have both cores active cura only gives you profiles to print with both cores together.
Since the 0.2 layer height is the only height both cores can print, cura hides the other one.
If you disable the AA0.4 printcore cura shows you all the profiles for the AA0.8 core, so that you can use the 0.3mm and 0.4mm layer height profiles.Edited by Gero
Just use "fast 0.8" and change layer height to 0.3 or 0.4. That's it.
There's no magic in the profiles. You don't need to tweak 5 other parameters - simply increase layer height some more.
